While the White House has declined to comment publicly, officials speaking on condition of anonymity say the administration backed down from a plan to designate the Brotherhood last month after an internal State Department memo advised against it because of the movement’s loose-knit structure and far-flung political ties across the Middle East.

The memo “explained that there’s not one monolithic Muslim Brotherhood,” according to one of the officials, who told The Washington Times that while the movement may well be tied to such bona fide terrorist groups as Hamas, its more legitimate political activities would complicate the terrorist designation process.

The Brotherhood has prominent political factions engaged — at least perfunctorily — in democracy in Jordan, Morocco, Tunisia and several other Muslim-majority nations, and the State Department memo coincided with high-level pressure placed on the Trump administration from at least one of them.
